Recent studies have suggested a proangiogenic effect of angiotensin-converting enzyme (ACE) inhibition. We hypothesized that such a proangiogenic effect of ACE inhibition may be mediated, in part, by bradykinin (BK) B(2)-receptor pathway. This study therefore examined the neovascularization induced by ACE inhibitor treatment in B(2) receptor-deficient mice (B(2)(-/-)) in a model of surgically i...

Objectives: This study was undertaken to examine recent trends in the use of angiotensin-converting enzyme (ACE) inhibitor therapy in patients discharged after acute myocardial infarction (AMI) and to identify clinical factors associated with ACE inhibitor prescribing patterns. Background: Clinical trials have demonstrated a significant mortality benefit in patients treated with ACE inhibitors ...

BACKGROUND-Chronic heart failure (CHF) impairs the endothelium-dependent, flow-mediated dilation (FMD) of small arteries. However, whether chronic angiotensin-converting enzyme (ACE) inhibition affects the impairment of FMD in CHF is unknown. We investigated the effects of long-term ACE inhibition on the FMD of peripheral arteries in rats with CHF and the mechanism(s) involved. METHODS AND RESU...

Angiotensin-converting enzyme (ACE) inhibitors elicit outside-in signaling via ACE in endothelial cells. This involves the CK2-mediated phosphorylation of ACE on Ser1270 and the activation of the c-Jun N-terminal kinase (JNK)/c-Jun pathway, resulting in an enhanced endothelial ACE expression. Because cyclooxygenase-2 (COX-2) expression is reported to be increased in subjects treated with ACE in...

OBJECTIVE To consider whether patients most likely to benefit from ACE inhibition in routine practice after acute coronary syndrome (ACS) may be identified from plasma natriuretic peptide concentrations. DESIGN Observational cohort study. SETTING Teaching hospital coronary care unit. PATIENTS 1725 patients admitted with acute coronary syndrome (56.3% ST elevation ACS; median age 67, range...

1. Severe anaphylactoid reactions have been reported in some patients treated with angiotensin converting enzyme (ACE) inhibitors during hemodialysis with a polyacrylonitrile (PAN) membrane. Generation of bradykinin via contact activation at the negatively charged membrane surface and reduced bradykinin breakdown due to ACE inhibition have been suggested as possible causes. This hypothesis was ...

Because part of the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors results from their protective effects on cardiac bradykinin (BK) metabolism, the purpose of this study was to define the metabolism of BK in normal and failing human hearts and to compare the effect of omapatrilat, a vasopeptidase inhibitor (VPI), which simultaneously inhibits both neutral endopeptida...

ACE-inhibitors and angiotensin receptor blockers (ARB) slow the progression of renal disease in non-transplant patients. A systematic review of randomized trials (n = 21 trials with 1549 patients) was conducted to determine the effect of ACE-inhibitor or ARB use following kidney transplantation. With a median follow-up of 27 months, ACE-inhibitor or ARB use was associated with a significant dec...

Hypertension is one of the very serious diseases and, recently, hypertensive patient longevity has been increased significantly. Therefore, the development of new antihypertensive drugs or bioactive compounds is very important to remedy or prevent hypertension. The antihypertensive angiotensin I-converting enzyme (ACE) inhibitor in water extracts from the brown-cultivar-fruiting-body of Hypsizy...

The appearance of cough in association with angiotensin-converting enzyme (ACE) inhibitors is thought to be related to bradykinin, and it has been speculated that the elicitation of adverse effects is genetically predetermined. Several polymorphisms of the human bradykinin B(2) receptor gene may be involved in ACE inhibitor-related cough. To investigate this possibility, we identified the -58 t...
